Description

Technical Field

[0001] The utility model relates to the field of material processing, in particular to a feeding system. Background Art

[0002] Lyocell fiber (which means soluble fiber) is a regenerated cellulose fiber produced by wet spinning with N-methylmorpholine-N-oxide (NMMO) as solvent. Waste can be naturally degraded, and 99.5% of the amine oxide solvent in the production process can be recycled and reused. It has extremely low toxicity and does not pollute the environment.
